The problem with Mini-Redirector is that it is full of bugs or rather odd
behavors. That it, when you try to use any other webdav server besides
theirs, which I guess their webdav server is called sharepoint. However
this looks more like part of their design and intentional instead of
simple bugs.
If you trace the request/response you will see that is asks for specific
files that would only exist on a windows server. Some of them are .ini
files and other GET requests for .exe which looks like a remote method
call. This is regardless of what the intial response of the server was to
the PROFIND at the root level. So it has a list of inital tasks that it
wants to do and expects the server to do them.
I'm sure after a few more versions it will not even fuction with any other
webdav servers besides windows. like most of their other client/server
products. A waste of time realy if you ask me to even try to follow it's
progress and bugs.
